21 cm Detector Day 3- May 21
Today we started off by drilling a few more holes into our cake pan and mounting sheet so that our antenna would match up correctly with the low noise amplifier. Below is a picture of some of the parts that are being used to build the 21 cm detector.
 |
| This shows the cake pan, which the low noise amplifier will go on the outside of, the antenna, which is a Styrofoam tube with copper tape wrapped around it, and the yellow square is pc board that will act as an insulator. The Styrofoam tube with copper tape will go on top of the yellow pc board inside of the cake pan. |
 |
| Next we needed to solder one piece of the copper tape to the SMA connector and another piece to the cake pan. Then we soldered a small cable to the SMA connector and inside of the cake pan as well. |
 |
| This is currently what the stand looks like. We still need to finish securing the mounting for the antenna. We also have to fix some of the soldering inside the cake pan. We then need to find a way to test the antenna to see if it works. If it does not work, we will need troubleshoot. We also want to find a way to clarify the directions to build the antenna. We will also try to better understand what a 21 cm detector actually does. |
